The default citation capability of LaTeX is not a true numerical
citation engine, rather it uses a mixture of labels/numbers. Thus
we now distinguish them: "numerical" always increments the bibitem
counter and uses its value as a numerical citation label, while
"default" only uses the bibitem counter when no label is provided.
LyX file format incremented to 471.
output, due to failure to clean the ids in the new citation stuff.
I've solved this by allowing the citation format information to contain
keys of the form "clean:key". This signals that we are to apply the
html::cleanAttr() function to the key before returning it. I.e., we
strip non-alphanumeric stuff, basically.
What was previously accomplished by wrapCitation is now customizable in the
layout files. What we provide by default here corresponds roughly to the
LyX 2.0 behavior.
Add a new layout syntax CiteEngine to define the citation commands
available for a given citation engine.
Also extend the CiteFormat syntax to allow more customization. This
mechanism, previously used to produce bibliography entries in the
citation GUI based on the BibTeX entrytype, is now also used to
produce the textual labels for citation insets in the buffer view.
Thus citation styles are almost completely customizable by modules.
Modules for the basic, jurabib and natbib engines are implemented.
Layout format incremented to 37.
